Constants

View Source 
const ContainerIDPrefix = "docker://"
View Source 
const DefaultNamespace = Namespace("default")

NOTE(nick): This isn't right. DefaultNamespace is a function of your kubectl context.

View Source 
const MagicTestContainerID = "tilt-testcontainer"

A magic constant. If the docker client returns this constant, we always match even if the container doesn't have the correct image name.

View Source 
const ManagedByLabel = "app.kubernetes.io/managed-by"

Functions

func ContainerIDFromContainerStatus

func ContainerMatching 

func ContainerMatching(pod *v1.Pod, ref container.RefSelector) (v1.ContainerStatus, error)

func ContainerNameFromContainerStatus 

func ContainerNameFromContainerStatus(status v1.ContainerStatus) container.Name

func ContainerSpecOf 

func ContainerSpecOf(pod *v1.Pod, status v1.ContainerStatus) v1.Container

func DuplicateYAMLDetectedError added in v0.17.0 

func DuplicateYAMLDetectedError(duplicatedYaml string) string

func ExtractPodTemplateSpec added in v0.1.0 

func ExtractPodTemplateSpec(obj interface{}) ([]*v1.PodTemplateSpec, error)

func FindImageRefMatching added in v0.2.0 

func FindImageRefMatching(pod v1.PodSpec, selector container.RefSelector) (reference.Named, error)

func FixContainerStatusImages added in v0.8.2 

func FixContainerStatusImages(pod *v1.Pod)

Kubernetes has a bug where the image ref in the container status can be wrong (though this does not mean the container is running unexpected code)

Repro steps: 1) Create an image and give it two different tags (A and B) 2) Deploy Pods with both A and B in the pod spec 3) The PodStatus will choose A or B for both pods.

More details here: https://github.com/kubernetes/kubernetes/issues/51017

For Tilt, it's pretty important that the image tag is correct (for matching purposes). To work around this bug, we change the image reference in ContainerStatus to match the ContainerSpec.

func FixContainerStatusImagesNoMutation added in v0.17.9 

func FixContainerStatusImagesNoMutation(pod *v1.Pod) *v1.Pod

FixContainerStatusImagesNoMutation is the same as FixContainerStatusImages but it does not mutate the input. It instead makes a deep copy and returns that with the updated status. It should be used over FixContainerStatusImages when the source of the pod is shared such as an informer.

func FragmentsToEntities added in v0.14.0

func IsContainerExited 

func IsContainerExited(pod v1.PodStatus, container v1.ContainerStatus) bool

If true, this means the container is gone and will never recover.

Returns the error message if the pod is unschedulable
